From 1993-2005 Millman was the off-staff creative director of HOT 97 in New York City, where she worked with Emmis Broadcasting General Manager Judy Ellis and Promotion Director Rocco Macri to transform the dance music radio station into the world’s first hip-hop radio station. Millman created the HOT 97 logo in 1994 and then redesigned it again in 1999, which is still the logo today.[8][9]

In 2009 Millman and Steven Heller founded the world’s first graduate program in branding at the School of Visual Arts[14] in New York City.[15] The school's inaugural class wrote and designed the Rockport book Brand Bible: The Complete Guide to Building, Designing and Sustaining Brands, and in 2013 the students designed and created branding for the Museum of Modern Art’s retail program, Destination: New York. In 2015 their project was to reposition the Kappa Middle School in Harlem and in 2016 they rebranded Mariska Hargitay’s Joyful Heart Foundation and the class of 2017 redesigned the identity of the Performance Space 122 in New York City.[16]
